DUMPING-CAB.

Specification of Letters Patent.

Application filed November 3, 1914. Serial No. 870,072.

To all whom it may concern:

Be it known that I, WILLIAM MORE, a resident of Pelham, Westchestercounty, State of New York, have invented certain new and usefulImprovements in Dumping- Cars, of which the followingis a specification.

My invention relates to railroad cars, and more particularly to thatclass of cars known D. SKID- as dumping cars, such as are used, forinstance,in railroad construction, for co-nveying ballast, fillingmaterial, and the l1ke to such places as the same may be needed, and

dumping the same upon or at the side of the but it will be readilyunderstood that cars constructed according to my invention may be usedfor other purposes plication Serial No. 830,744, filed April 9,

The invention consists in the novel construction, arrangement andcombination of various devices and parts, as shown in the accompanyingdrawings and hereinafter particularly described.

In the said drawings,Figure 1 is a side elevation of a car constructedaccording to my invention; Fig. 2 is a sectional view thereof taken onthe line 2-2 of Fig. 1-; and looking in the direction of the arrows;Fig. 3 is a detail view, hereinafter more particu larly described, Fig.4 is a sectional view taken just to'the left of the flange 80 shown inFig. 5 and looking from the right, and Fig. 5' is a perspective anddiagrammatic view showing certain positions of my invention.

In carrying my invention into effect in the embodiment thereof which Ihave selected a citizen of the United States, and

for illustration in the accompanying drawlngs and description in thisspecification, I provide'for the lower part of the car-a runnlng gear ofthe common or any suitable form of construction, comprising the usual.

. Patented-Feb.15,19 16.

sills and; bolsters, which are mounted on. 1 two bog1e trucks, provided,with journal boxes, numbered 13 in the drawings, which form thebearings for "the ends of the axles of the wheels '14. a v i The upperor carrying portion of the car is pivotally elevated above the runninggear above referred to by the construction here-. after to be described.This carrying portion. comprises a floor 15, to the under side of Ywhich are secured spreader plates provided with trunnions 19, bearing inopenings 18.

in spreader plates 17. The floor is provided with ends 51, and sides 47and ,8, these sides preferably being capable of'being ele-. vated fordischarging the load, but as this I feature is described and claimed ina co pending divisional application of said ap: plication No. 830,744,they are not particularly described, or claimed, herein. v

When the body of the car is in its normal erect or carrying position, asshown in the drawings, it is so held by the chains 60 and 61'whi'ch areattached to the body of the car, and which pass downward and under andaround pulleys 63 and 62 respectively and then pass horizontally to theend of the carand are woundfor a portion of their 7 length around awindless shaft 36. It is desirable that other supporting means be alsoused to hold the body in its erect orflca'rrying position but as meansfor this purpose.

are described and claimed in said co-pending original application No.830,744, they are not particularly shown, or described and claimed inthis application.

It is desirable that the tilting of the car body be effected by powermechanism. Such mechanism may consist of a cylinder 56 for compressedair or the like, operatively connected withthe .car body in such a wayas to tilt the same when the pistonof said cylinder is moved, the chains60 and 61 being of course first released. As this mechanism is describedand claimed in applicants J said co-pending divisional application, itis merely mentioned here. As heretofore stated, the said chains 60 and61 are wound for a portion of their length in the same direction aroundthe Windlass shaft 36. Referring particularly to the detail view Fig. 3it will be seen that the end of this shaft 86 is squared, so as toreceive a crank for rotating same to wind up the chains when it isdesired to restore the car body to its normal position after dumping,and it will be obvious that upon rotating this shaft and winding up bothof said chains thereon until they are quite taut, the upper side of thetilted body will be drawn down by one of the chains, the slack oftheother chain being at the same time taken up, and that when the bodybecomes level both chains will be tight. When this occurs the car bodywill be held in its horizontal ,position by the two chains, which willbe held from unwinding by the ratchet mechanism now to be described.

The shaft 36 is journaled in the brackets 32, and to each of thesebrackets is pivoted an arm 70. Pivotally secured to the outer end ofthese arms 70 are pawls 31 and 31 At the same points are pivotallysecured the lower ends of rods 72, the upper ends of which are pivotallysecured to levers 75, having handles 25. Each lever 7 5 is pivotallysecured in a bracket 74, and it has a pivotal lock 27, secured to thelever at 28, the lower end 29 of which engages with a rack provided withnotches 30, being held in engagement therewith by a spring 31, in amanner which will be well understood.

There are two ratchet wheels 33 and 33 (provided with flanges 80, 81, 82and 83) on the shaft 36, the teeth of which are in register with eachother a pawl for each ratchet and operating devices therefor. The saidpawls are of different lengths (see Fig. 4) so that at any one time onlyone of said ratchets is in engagement with a pawl. When one of the pawlsis disengaged from its corresponding ratchet wheel the shaft is free tounwind to the extent of one-half the distance between the teeth, beingstopped after rotating to that extent by the other pawl and ratchet. Ifthen the second pawl and ratchet are disengaged and the first throwninto engagement, the shaft can unwind another half-tooth, and so on.This enables the car to be either tilted to its full extent quickly, bydisengaging both pawls and ratchets, thus allowing the restraining chainto quickly unwind to the fullest extent, or'to be tilted a very smalldistance and held there or successively tilted more and more step bystep,by disengaging said pawls and ratchets alternately, keeping one setin engagement while the other set is disengaged. As both chains arewound upon the shaft in the same direction, it follows that both aretightened and both released at the same time. As both chains areslackened, the car is free to tilt in whichever direction is desired.

The operation and advantages of my invention will be readily understoodfrom what has been above said with regard to its construction.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent is as follows:

1. lin a dumping car, the combination with a car body, running gear, andmeans adapted to pivotally support said body upon said running gear; ofmeans adapted when in one position to maintain said body horizontal andwhen in another position to allow said body to tilt, said meanscomprising a chain secured to said car body on each side of the middleline thereof, and means adapted to hold or release both of said chainsat the same time.
